After introducing the ground breaking Air Penetrator AP121 computer fan in 2010,
SilverStone engineers have created another breakthrough design that further
refines the air channeling fan concept. Typical case fans, no matter how quiet
when spinning on their own, usually produce clear audible noise when installed
as intake case fans. This higher-pitched noise is the result of air turbulence
generated between fan blades and the case's intake grille. The AP123, on the
other hand, uses fan blades with three distinct shape and sizes to create uneven
airflow. This design may be slightly louder when the fan is spinning on its own,
but when installed as a case fan, it is capable of reducing noise frequency by
up to 66%. Besides noise reduction, the unique fan blades are also designed to
generate high airflow and static pressure simultaneously for great performance.
Mated to the same air channeling grill made famous by the AP121, the AP123 is
one of the best computer intake fans on the market.

Pros

Summarybought two to suck air from outside through two hot swappable HD cages to keep drives cool. I'm happy with them, air noise through cages should be expected, tells you they are moving lots of air.

Pros

SummaryI own three of these, and I must say I am liking them. Moves a lot of air, and the cone of air reaches very far. Excellent for intake fans so that the cool cone of air reaches CPU heatsink or graphics card.

Comparing to Noctua NF-P12 running at 12 volts (1300rpm), these are much louder when running at full 12 volt (1500RPM). However, if you undervolt them to 9 or 7 volts, they are very quiet.

SummaryI these pulling air off my radiator (horizontal) at 5 VOLTS AND THERE THE LOUDEST THING IN MY CASE!!!!!! I saw I review of these and the looked quiet and liked the color but.... just horrible. I haven't tried in push position yet... good thing I got them at 10 a piece.
